*13 Week : REPORT PSM 1

This week is the last week before the presentation week, so there are so many things that had to be complete by this week. Such as;


#Literature review : The related work
There is some related work to my Air Quality Monitoring. The function of all this work is same, which is to monitor the air, but in different method.

Temporal Air Quality Monitoring Using Surveillance Camera

The aim of this work is to develop a state-of-art reliable technique to use surveillanc camera for monitoring the temporal patterns of PM10 concentrations in the air. In this work an internet protocol (IP) network camera was used as an air quality monitoring sensor. The figure below show the IP network camera and the overview of Temporal Air Quality Monitoring.

Hierarchical Air Quality Monitoring System Design

The aims of this work is to build the prototype system by hierarchically deploying terminal sensor nodes inside the smart buildings of each floor and data collection units and routers in the open spaces between smarrt buildings, and transferring the sensor thing data back to the information processsing center for real-time information. The information processing center is through ZigBee wireless protocol. The detection of air is by CO, SO2, NO, NO2 and PM2.5 sensors. The figure show the  MQ135 sensor 2.5 sensor.

Air Quality Monitoring Using Remote Sensing and GIS Technologies

This is the new method, which is integrates satellite remote sensing and Geographical Information System (GIS). It can be used to continually monitor air quality at micro-scale level.

I had study this three related work, there are the comparison between this three and my project.

#Literature Review: Competitive Analysis
Competitive Analysis is the product that already in the world market with the same function of my project, to monitor the quality of air.

Air Mentor	DC1100 Air Quality Monitor By Dylos	Airassure PM2.5 Indoor Air Quality Monitor
Air mentor is a product from China. The founder of this product is CoAsia Microelectronics Corp. The purpose of Air Mentor is to monitor the concentrations of VOC, particulate matter, temperature and relative humidity. This product are indoor air monitoring, cannot use it outside of the building.	The founder of DC1100 Air Quality Monitor is Dylos Corporation. DC1100 features technology and engineering that allows monitoring of indoor air quality with an LCD screen that provides small and large particle counts with a dynamic bar graph showing actual count reading. Multiple modes including minute, hour, day and monitor to evaluate your air quality and store up to 30 days of air quality history for review.	This item is produce from TSI, the world pioneer in molecule estimations, the AirAssure PM2.5 Indoor Air Quality (IAQ) Monitor can give continuous, dependably exact estimation of indoor PM2.5 dust focuses, one of the best wellbeing dangers today. The AirAssure Monitor is the savvy on-the-divider instrument to address the issues of all the partners in a building.

I had search and study about this three product, and the table below show the comparison of all this product and my project.

Characteristics/Type	Air Mentor	DC1100 Air Quality Monitor by Dylos	Airassure PM2.5 Indoor Air Quality Monitor	Low Cost Air Quality Monitoring System
Sensor	Particulate matter, Humidity, Temperature	Dust Sensor, Smoke Sensor.	Light Scattering Photometer	Particle, Temperature and Humidity
Communication	Bluetooth	No information	Ethernet	Wi Fi
Location	Indoor	Indoor	Indoor	Indoor & Outdoor
Price	RM700.00	RM799.96	RM3980.00	RM250.00

From the table, show the comparison between the element of Sensor, Communication, Location and price. The biggest different between all this element is the price. The product out there is very high in cost. That why my project will attract people to have it when it in the market. InsyaAllah :D
